What's the vehicle transportation process like?

I placed a deposit for a car on the east coast (I'm in Southern California) - can anyone share what the transportation process is like in terms stages/communication? Does the car just show up one day without getting any emails, or are we told when it's loaded onto a (train? Truck?)

I've been told because of the EOQ backup, mine probably won't show up this month, but any detail on the process would help keep me occupied
